K 1 Claim. l

This invention relates to a device for ejecting tooth paste from a conventional collapsible .tube onto a tooth brush in the correct amount and without all the waste and botherencountered in the present hand system of squeezing the tube.

An important object of the invention is to provide a device wherein tooth paste is dispensed upon a tooth brush in response to arapid insertion and removal oi theV tooth brush in the device.

Another object of the invention is to provide a tooth paste dispenser which includes a compartment for receiving the collapsed end of the tube and a means for directing-this collapsed end continuously into the compartment.

A further object of the invention is to provide a tooth paste dispenserA which is relatively simple in design and construction, inexpensiveg'and very easy to assemble andvoperate. c

These, together with Various ancillary objects and features of the inventionwhich will later become app-arent as the following description proceeds, are attained bythe device, a preferred embodiment of which has been illustrated by way of example only in the accompanying drawings, wherein:

Figure l is a perspective View of the device;

Figure 8 is a Sectional View taken on the line 8-3 of Figure 9;

Figure 9 is an enlarged fragmentary vertical sectional view similar to Figure 7 and showing the dispensing of paste on a tooth brush; and,

Figure 10 is a front elevational view of the device.

Specific reference is now made to the drawings. In the several views in the accompanying drawings and in the following specification reference characters indicate corresponding elements throughout.

The device comprises a vertical hollow casing I having front and rear walls I2 and I4 interconnected by side walls I and I8, the casing being open at its bottom end as at 20, The casing includes a removable top closure 22 and an apertured bracket 24 for receiving a suitable fastening pin 26 for securing the casing to a supporting wall 28. The front wall is provided with a vertical slot 3i) for a purpose soon to appear.

Journaled in the side walls It and I8 adjacent the upper end of the casing is ya pair of spaced rollers 32 and 34, one of the rollers 32 including an end extending through the wall I3 and carrying at this end a knurled knob 36 for turning the roller. The knob further includes a, ratchet 33'and a pawl di) for retaining the roller 32 in an adjusted rotational position. The other roller 3Q is mounted on brackets l2 which are urged by springs 44 toward the roller 32. A conventional collapsible tooth paste tube 4S is provided which is received at its upper end between the rollers which apply squeezing pressure to the tube as will be readily understood.

The tube includes a threaded neck portion lie from which the usual cap has been removed, the neck portion being removably retained in a threaded aperture of the top wall 52 of a housing 54 which is vertically slidable in the casing Iii and further includes side members 56 and a bottom wall 58. The housing is slidable between the side walls I6 and I8 of the casing, the front wall I2 and `a vertically extending partition E@ which is in turn spaced from the rear wall I4 to provide a collapsed tube-receiving compartment 62. As the paste is squeezed from the tube, the collapsed portion 611 thereof enters the compartment being directed therein by an arcuate baiile 56 secured to the rear wall I 4 and overlying the roller 32.

The top Wall of the housing 54 is provided with dove-tail grooves 68 for slidably receiving the dove-tail tongue 1D of a slide bar or closure l2, the latter further including an elongated slot M extending along only a portion of the length of the bar. Laterally extending pins 'i6 are carried by the side edges of the bar and anchor one end of a pair of springs 18 which are anchored at their other ends to pins 8U secured to the inner surfaces of the side members 56 of the housing 54, the springs normally urging the slide bar toward the front wall I2 of the casing so that the unslotted member 92 having side walls 94 and a rear wall 96. Pivoted for vertical movement as at 98 to the rear wall 96 is a dog |06. The side walls 94 include lateral pins |02 to which are anchored one end of a pair of springs |04 which are in `turn anchored to pins |06 carried by the side walls 56 of the housing 54. The springs urge the slidable member 92 toward the front of the casing.

In practical operation, the neck portion 48 of the tooth paste tube 46 is `threaded into the aperture 50 of the housing 54 and the tube and housing are slid into the casing ||J, the upper end of the tube being received between the squeeze rollers 32 and 34. The knob 36 is rotated to apply pressure to the tube which would normally urge the paste contents through the aperture 50 but for the fact that the unslotted portion 82 blocks the aperture 50 and prevents dispensing of the contents. A tooth brush |08 is then pushed into the housing 54 through lthe slot 30 at the front wall of the casing until the end opposite the handle strikes the rear wall S6 of the slide member 92 pushing the latter toward the partition 60 against action of the springs |04. The dog |06 engages the lip 84 of the slide '|2 and moves the latter toward the partition whereupon the slot 'i4 underlies the aperture 50 uncovering the same for the full movement of the tooth brush toward the partition, during which movement paste is dispensed on the brush as shown clearly in Figure 9, Because of the downward inclination of the bottom wall 86 of the housing 54, the dog |00 becomes disengaged from the lip 84 when the rear wall of the slidable member approaches the partition and the slide 12 snaps back toward the front wall I2 to immediately cut oi the further dispensing of paste on the brush. Removal of the brush will allow the slidable member to return whereupon the pivoted dog will reengage the lip 84 of the slide 'I2 for repeat operation. As the contents of the tube are consumed, the housing 54 moves vertically up the casing I0 and the collapsed portion 64 of the tube is directed by the arcuate baille 66 into the compartment 62 behind the partition 60. Thus, tooth paste is dispensed in `the present de- 4 vice by a quick insertion and removal of the tooth brush in the casing whereby only a predetermined amount of paste is delivered on the brush.

In view of the foregoing description taken in conjunction with lthe accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended bythe spirit of the invention as herein described andthe scope of Ithe appended claim.

Having described the invention, what is claimed as new is:

A dispenser comprising a casing for the reception of a collapsible paste container, means for ejecting paste from the container and means for controlling the discharge of the paste, the second named meansncluding a housing in the casing connected to the container for receiving paste therefrom, a spring closed slidable closure for the container in the housing, a member slidable in the housing for receiving .a toothbrush and operable thereby, and means releasably connecting the closure to ,said member for actuation to open position thereby, the last named means including a lip on the closure, and a dog pivotally mounted on the member and operatively engageable with said lip when said member is moving in one direction in the housing.
